5 State of Kansas, have invented certain new and useful.Improvements in Acetylene-Gas Generators; and I do hereby'declare the following to be a fulh clear, and exact de scr ption of the'invention, such as will en 10 abl others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in acetylene generators.

The object of the generators and to provide a simple, practical, and comparatively inexpensive acetyleiie generator equipped with a valve for automaticallycontrolling the vdischarge of from the carbid holder adapted to beoperated-bythe bell or receiver when the gas therein 'is'nearly consumed.

A further object of the invention. is to provide an automatic controlling valve accurately discl'iarge the desired amount of carbid into the water tank and capableof effectively preventing more than a single. charge being delivered at one time and of preventing any pinching of the caroperation so that the free dis charge ofthe carbid will be assured.

A further object of the invention is to provide an acetylene gas generator which will be perfectly saie'and reliable and not 35 require an 'auton'iatic relief or safety blow Furthermore it is the object of the invention. to, provide an acetyli'sn'e gas generator adapted to be easily cleaned so that mixer or agitator for stirring the water will be unnecessary.

With these and other objects in .view the invention consists in the construction and novel"combination and arrangement of parts described, illustrated -in the accompanyingdrawings and pointed out in the claims heretoap'pendethit being an derstood that-various changes in the form, proportion and minor details of construction to without departing from Specification. oi Letters Patent.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, 1 designates a Water tank of any desired construction and capacity provided at the top with a central opening2 and having upwardly extending spaced concentric walls or shells 3 and a surrounding the opening and forming a Water seal 5 into which a bell or floating receiver 6 extends. The inner wall or shell 3 supports a carbid holder 7 provided at its upper portion with outwardly extending hooks 8.

which engage over the upper edge of the inner shell or wall 3 of the Water seal, whereby the carbid holder is removably supported in position over the water in the tankl. The tank 1 is provided at the botto nwith a sludge valve 9 and the bell-6' is provided at the topovith a flared aperture 10 and a removable screw cap adapted to be taken oil to permit the bell to be readily lifted out of the water seal when it is desired to fill the carbid holder 7. by removal of the screw cap a. pressure in the valve and the atmospl'umic pressure are equalized thereby allowing the same to be easily removed. The carbid holder which has a'tapared lower portion 12 is provided. at the top with a filling opening .13 which is normally covered by a pivoted closureld but any suitable closure may of course be employed the filling opening of the carbid holder is located within the bell 'lhc tapered lower portion 12 of the carbid holder has flattened walls which are inclined downwardly, "and it is provided with a bottom outlet 13 preferably formed by cutting away one of. the walls of the lower portion 12 but the said outlet 13 maybe formed in .any other desired manner. The walls at the .perforate and the carbid holder is provided 5 at the,'bottom of the outlet with a transverse pintle ll which pivots a (:Ontrolling and dumping valve to the carbid holder. The valve 15 is composed of spaced sides and a connecting bottom portion which is extended at the back to form an upwardly curved rear wall 16. The pintle 1i extends through the side walls of the carbid dumping and controlling valve which valve has a tapered portion 17 projecting in advance of the trans verse pintle 1e 'and forming a discharge mouth or spout. The valve 15 which extends downwardly and rearwardly at an inclination as illustrated in Fig. 1 of the. drawings when in its non-feeding position s provided with a plate or partition 18 fixed to the side walls of the valve, and extending across the same in parallelism with the bottom of the valve. i

The plate 18 which extends rearwardly from the transverse pintle forms a closure for the outlet of the carbid holder and is adapted to be swung upwardly to the dotted position illustrated in Fig. 2 of the drawings to cut oil the 'flow of the carbid from the -arbid holder into the valve when the valve is moved to its dumping position. The carbid controlling and dumping valve is also provided with av rear hinged section or wall it) consisting of a plate connected at its lower edge to the rear wall 10 by a trans verse pintle :20 and extending entirely across the space between the sides of the valve and extending upwardly from the rear wall 16 in a perpendicular position which is maintained by the rear hinged wall section or member 19 during the opening and closing movement of the valve, and tear of the carbid from being forced outwardly over the rear wall of the dumping valve during the movement of the dumping valve will be entirely eliminated. lVhen the valve is being dumped the rear hinged plate or member lfl'moves away from the carbid holder, the plate 19 moves backward leaving the carbid and freeing the same within the valve and permitting a tree discharge of the carbid from the valve. When the valve is returned to its closed position the hinged rear plate or member if) regains its initial position as the carbid refills the valve. The carbid controlling and dumping valve is automaticall operated by the bell (S which is adapted to engage a roller 21 mounted on one end of a lever 22 in a fork or bifurcation there f and it is adapted to ride against the inner face of the top of the bell (3 which in moving downwardly through the consumption of the gas contained within it is adapted to oscillate the lever 23, swinging one arm downwardl) and raising the other arm of the lever 22. The lever 22 is pivoted intermediate of .its ends to a projecting support 23 which extends upwardly from the top of the carbid holder and the pivot of the lever 22- is located at a point between the center and one end of the lever, the short arm of the lever being connected to the" upper end of a rod 2i which extends through the carbid holder. The carbid holder is provided with a vertical tube which extends from the bottom to the top of the carbid holder and in which the rod 2% is freely movable The lower end of the rod QetiS provided with? a fork .26 for connecting the rod with th carbid controlling amtdumping valve. The? sides of the fork or bail are provided at their lower terminals with inwardly projecting pivot portions :27 which engage perforations of cars 28 secured to the exterior of the valve 15 atthe sides thereof and having the perforations located in the rear edge of the transverse plate or partition 18. The rod 24; is connected with the wall section or plate lil b v a link 2 of approximately U-shape, the transverse connecting portion passing through an eye 30 of the said wall section or plate '19. The wall section or plate 19 is provided at its upper edge with the said eye 30 and the sides of the link 29 are provided with eyes 31. which receive the transverse portions of the fork or bail :26 whereby eter to permit the necessary play of the connccting rod 2-1- in the opening and closing movement oi. the valve. The acetylene gas generator is equipped with a filter 32 mount ed upon the tank 1 at one side of the water seal aml comprising a cylindrical casing, a series of i'rusto-conical ballleplates 33 and filtering material itllocated within the upper cml of the casing above the baflle plates. The filtering material ma v consist of pack i'clt. wool or any other suitable material and it is adapted to remove any of the scdiincnt of, the ash from the gas before the same cnlcrs the gas pipe $33. The. lower portion of the casing of the fillcr contains water. the level of which is maintained constant b an overflow pipe Ito mounted on the tank and extending into the filtcr and depending into the said tank below the surface of the water contained within the tank. The gas to be cleaned or filtered passes into the casingol' the filter through a gas inlet pipe IET secured at its lower end to the tank and located above the surface of the water within thcsamcand provided at the top with a return bend 23 and having a depending leg Zlf extending into the water of the filter. The depemling leg 3t) 04.. I.

51 at its upper end.

the gas inlet pipe is provided with'submerged perforations preferably about one-sixteenth of an inch in diameter and adapted to permit the gas to escape from the inlet pipe and hubble through the Water. .The depending portion or leg 39' also carries a funnel-shape defiector and separator 41 presenting inclined sidesto the bubbles of gas and adapted to cause the same to rise in a separated condi tion to the surface of the water within the filter. The baflie plates which are adapted to .dry the gas and remove the water therefrom are proiiided with openings 42 and 43 alternatel 1 arranged at the center .and sides of the'baille plates and adapted to cause the 'gasto pass'over the said plates. The filter ing material removes all the ash from the gas and the pipe 35 which receives the clean gas is connected with a pipe 44 leading to thelights or other means of consumption of the gas, a stop cock 4-) being provided. for cutting out the pipe 44 to prevent any air entering the same when refilling the carbid holder. A gas pipe 35 is also connected with a vent pipe 46 having a cut out cock 4? and adapted to permit the escape of air from the acetylene gas generator. after-the carbid holder has been refilled. A drain pipe 48 extends downwardly from the pipe 44 to a point below the surface of water within the tank to permit any water of condensation to find its way back into the tank should it pass beyond the filter. The filter is provided at the bottom with a drain plug 49 and it has a filling tube 50 depending from the top ofthe filter 'and extending through the batfie plates and provided with a closure plug This will enable the water and sediment to be drawn oil" from the filter and clean water placed therein. Sahould the water through accumulation of sediment within the filter rise above the upper end of the overflow pipe 9 it w'll flow into the water tank and a constant level of the water withinthc filter will be maintained.

In order to return the valve of the carbid holder to its closed position, the said valve is provided with a weight 52 of anydcsircd construction mounted upon the rear portion of the valve at the bottom thereof and "adapted to positively close the said valve aftor the contents have been discharged and the operating mechanism released by the raising otthe bell. The acetylene gas gen- 'erator operates in the usual manner to probell and release the valve and permit the same to close.

it will. be seen that theacetylene gas generator is easily cleaned, that the carbid con- I a'.carbid holder having an outlet in one of its sides near itslower end, a valve located below the lower end of said holder and extending in two directions beyond said side and having a receiving and a discharging end. means establishing a pivotal connection between said valve and holder" at a point to one side of said outlet, said valve normally occupying an inclined position with ils receiving end lowermost and on that side of the holder in which the outlet is located, means for raising said receiving end in the direction of said side of the holder to discharge the contents of the valve. a plate carried by said valve for cut ting oli' the supply of carbid when said valve isin discharging position, a vertical rear wall hinged at its lower end to the re.- cciving end of the valve, and means for supporting the upper end of said Wall and for holding said wall against movement bodily in thedirection of said side of the holder during the movement of the valve into discharging position whereby to prevent the packing of the carbid between said rear wall, said side of the holder and said plate so as to insure a free and complete discharge of the carbid from the valve.
